Fietje Sensor- & Optoelektronik GmbH

Booth number 4105-23

Fietje is a supplier of customer-specific LEDs, photodiodes and phototransistors for high accuracy optical sensors used in industrial automation and obsolete part replacement.

About us

The company Fietje Sensor- & Optoelektronik GmbH was established in 1994 as a distributor for optoelectronic parts of OPTEK Technology Inc. USA. In 2000 we changed our field of business to our own designed products. Fietje is a R&D fabless company with OEM known for its optoelectronic parts with high customized properties.

The product range includes highly selected binning light emitter diodes, photo diodes and photo transistors in the range of 2Фe 3°...130° viewing angle, which are offered in many THD (e.g. bended and cutted) and SMD packages. The design of high accuracy tools for production and the high binning performance guarantee the high quality of our products.

We offer the development of chip design and package design according to the customer request.

In our test laboratory we have a broad range of testing equipment for all necessary measurements of opto-characteristics in the wavelength range of 200 nm up to 4000 nm. We offer analysis of obsolate parts or others for replacements with higher accuracy or performance. Life time and ambient condition tests are also available.
